Strategic approach to climate change

Reporting and tracking emissions

We have been estimating and reporting our GHG emissions since 1995, and regularly review our reporting practices against best practices, global standards and government requirements. By applying the latest and most rigorous standards, we continually improve TransAlta’s GHG reporting systems and practices.

In 2004, we reported GHG emissions from our Alberta coal plants to Alberta Environment, under a reporting program for large emitters (facilities emitting more than 100,000 tonnes of CO2). We also reviewed our reporting methods against guidelines for a national GHG reporting program for large industrial emitters, scheduled to start June 2005. Results of our review show we are well positioned to meet the new national reporting requirements.

In November 2004, we commissioned CH2M HILL Canada to audit emission methodologies we use to measure the GHG benefits of decommissioning units 1 and 2 of our Wabamun coal plant. This report will be finished in early 2005. We plan to apply the report’s findings to further improve GHG reporting practices at our different coal plants.
